YARN REEL.

Application filed July 22, 1925, Serial No. 45,344, and in Switzerland August 9, 1924.

There are already in existence yarn reels the circumference of which can be altered by means of the spokes which are fixed only to the front side ofthe nave flange these are moved Within a certain angle from the point of attachment by means of guiding plates. The disadvantage of this device is that the angle within which each spoke can be moved is comparatively small, as the joints of the adjoining spokes, which project from the nave flange, limit the angle within Which each spoke can be moved.

In the present invention this disadvantage is diminished, and a greater degree of alteration in the circumference of the yarn reel is rendered possible, in the following way: on each nave flange the spokes are placed alternately on the inner andthe outer side of the nave flange, means being provided by which the spokes can be made to move ontheir pivots.

The sketch shows the invention applied in practice. Fig. 1 shows part of the yarn reel in vertical section, Fig. 2 a side View from the left of Fig. 1, Fig. 3 is a section on line O-D, Fig. 1, Fig. 4 a side view of a guiding plate for moving and holding the reel spokes, and Fig. 5 a side view of a nave flange of a reel, with the spokes, the guiding plate having been removed.

On the flange 1 of the nave of the reel 2 the successive spokes 3 are mounted alternately on the outer and the inner side of.

the flange their ends beingbent at right angles and entering holes in the nave flange 1. For example, in Fig. 5, the spoke 3 is on the outer side, the next spoke 3 on the inner side, the next 3 on the outer side again, and so on. The result is that the mobility of a spoke is not bounded by the points of attachment of the spokes next to it, but only by those of the next but one. The spokes thus have a much greater mobility than if they were all fixed on one side of the nave flange. On the outer side of the nave flange of the reel 1 there are guiding and holding plates for the spokes 4. 4, the arms 5 of which have slots for guiding and holding the spokes. These plates 4, 4, are fixed on the square shaft 6, by means of which they can be turned round in relation to the nave, and screwed up to the nave flange by the nut 7.

The ring-shaped runner a is formed of two parts, not counting the connecting parts.

One of theparts is a cap 11 with a corrugated flange forming pockets for the balls '20 which are placed freely in it, and which serve tobrake the reel. The weightof each ball is directed vertically downward and acts to retard the rotation of the reel, 1. e.,

brake it, with a constant load. The second part of therunner is formed by the guiding plate 4, which separates the cap 11 from the nave. The guiding plate 4 has arouate slots 8, 8. The cap is firmly connected with the nave flange by the screws 9 and pins 10 which pass through the slots, while at the 7 same time plate 4.

If the diameter of the reel is to be it does not press onthe guiding altered,

this is done by loosening the nut 7, and thus having spokes pivoted alternately on op-.

posite faces of said flanges, a guide plate on one face of each flange having slotted lugs in which the spokes are guided, and means to urge said plates against the spokes lying between them and said flanges.

2. A yarn reel, comprising a shaft, a flanged nave thereon having spokes pivoted alternately on opposite sides ofthe flanges of said nave, a guide plate 'on the exterior face of each flange having slotted guide lugs in the slots of which the spokes are guided. and a screw on said shaft to press said plate against the flanges.

3. A yarn reel comprising a shaft, a flanged nave fixed thereon having spokes pivoted alternately, on opposite sides of the flanges of the nave, a guide plate on the exterior face of each flange having slotted guide lugs in the slots of which the spokes are guided, means to press said plate against the pivoted ends of the spokes on the exterior faces of said nave, a pocketed ball carrier secured to said nave and balls therein lying against said plate.

4. A yarn reel comprising a shaft,

flanged nave fixed thereon having spokes pivoted alternately in opposite sides of said flanges, an arcuately slotted guide plate on the exterior face of each flange having 5 slotted lugs, in the slots of which said spokes are guided, a corrugated ball carrier secured to sald nave through the arcuate slots of said plate to. permit relative movement of plate to said carrier and nave, said balls lying against said plate. r

In testimony that I claim the-foregoing as my invention, I have signed my name.
